Description

The desired ratio of the amplitudes of the pulses is determined from the difference in the number of oscillations of the catenated oscillator, switched on by the front and off by the falling edges of each amplitude measured pulse.

Дифференцированные импульсы управ .т ют генератором калиброваннойThe measured impulses on the necessary amplification in the amplifier Y are limited in amplitude by the maximum in the limiter O, and then differentiated in the differentiating device D. The differentiated pulses are controlled by a calibrated generator

Распределительное устройство Р. представл ющее собой обычный бинарны пересчетный каскад, посылает поочередно пары имшульсов, полученные при дифференцировании измер емых сигналов, в счетчики Ci и Cz дл  их отпирани  или запирани . Счетчики фиксируют количество импульсов, генерируемых генератором во врем  прохождени  через схему соответствуюииьх измер емых имнульсов.Part 1 1 / so that the front edge of each measured pulse unlocks the generator, and the rear edge closes it. The switchgear P., which is a conventional binary recalculation cascade, sends alternately pairs of pulses obtained by differentiating the measured signals to counters Ci and Cz for unlocking or locking them. The counters record the number of pulses generated by the generator during the passage through the circuit of the corresponding measured pulses.
